Thank you Bob and others for the reply and links!

Well I just learned that noise has an effect on the received signal. I'm not sure what this outside noise component comes from, I actually didn't even know there different categories of sources :S, but my question comes from a demonstration where a signal that is sent from a sender to a receiver...

This is just a general question. I'm starting to learn about sensors, but I don't understand the physics behind how potential can be created from noise. Thank you for your time

Hello, I am trying to understand how noise affects the potential measured across a certain point of a circuit. If we have two alternating voltage sources in a circuit, I understand that the "sum" of the potentials provided can affect the potential at the point of interest. However, I am...

Hello, First of all, I'm not sure if this is in the right section, and I know it's probably a very basic question compared to all you levels of knowledge. So please if it isn't in the right section, let me know where I should post it, and if not thanks in advance for the help. I'm trying...

oh alright! thank you

Ok, but what about the sum of ((-1)^n)/n? Doesn't the divergence test say that this sum diverges because of the alternating 1, while the series converges with the alternating series test..

Can the Test for Divergence (limit of an->infinity not equal to zero) be used on an alternating series? For example, if a series has a (-1)^n term. Can we assume that since the limit of that term does not exist, then the series is automatically diverging?
